9. E-Textiles and Wearables II#

This week I worked on resistor embeded on a cloth that can turn on a LED and regulate the intensity of the LED Materials: LED Arduino Conductive thread 10 ohm resistor cables

Research Attitiny programation#

First trial


It didnt work because the conductive thread was so far from each other

Trial 2, i tried a closer stitch

Arduino Code#

// notes in the melody:
int melody[] = {
  NOTE_C4, NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, 0, NOTE_B3, NOTE_C4
};

    // note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
 4, 8, 8, 4, 4, 4, 4, 4
};

void setup() {
// iterate over the notes of the melody:
 for (int thisNote = 0; thisNote < 8; thisNote++) {
// to calculate the note duration, take one second divided by the note type.
//e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
int noteDuration = 1000 / noteDurations[thisNote];
tone(8, melody[thisNote], noteDuration);

// to distinguish the notes, set a minimum time between them.
// the note's duration + 30% seems to work well:
int pauseBetweenNotes = noteDuration * 1.30;
delay(pauseBetweenNotes);
// stop the tone playing:
   noTone(8);
 }
}

void loop() {
 // no need to repeat the melody.
}
